Reinforced concrete core walls form the backbone of millions of buildings internationally, bracing the structure against wind and earthquake loading. Due largely to plan asymmetry, a torsional response of a building is possible, where the core wall will resist the twisting actions. There is currently no evidence for the torsional capacity of reinforced concrete U-shaped core walls, which are a popular wall geometry used in construction practice. An experimental campaign will be soon conducted in the laboratory LEMSC of the institute iMMC at UCLouvain, Belgium, to test three large-scale reinforced concrete U-shaped walls subjected to different combinations of flexure and torsion. A blind prediction competition was organised by the authors to estimate salient behaviour and performance characteristics of the walls subjected to pure flexure and pure torsion. This paper presents a summary of the experimental campaign and some blind predictions by the authors using finite element modelling. These predictions, as well as others submitted for the competition, will be compared to the experimental results during the conference presentation. |
